Crown Battery
390 Ah 6V Sealed AGM
Deep Cycle Batteries - Qty 16

We have partnered with Crown Battery to sell these batteries in pallets of 16 - perfect for a backup battery option for your grid tie solar system! 


FEATURES - What makes Crown Battery stand out among the competition?:

  • Thicker, fuller frame and grid design ensures structural integrity throughout product life, and greater cycle life
  • Inset "Centerline" plate lug feature ensures best available electrical efficiency during charge and discharge
  • Signature "Diamond" grid wire design optimizes grid surface area within the plate core, for improved active material adhesion, as well as minimal exposure to electrolyte, which reduces premature grid corrosion
  • Higher antimony content for high performance cycling, and increased current flow
  • Higher density lead oxide on the plates , through industrial oven-curing process, gives greater durability to the plates which leads to longer discharge times and longevity of the battery
  • One piece solid cast-on strap with integrated terminal post and through-partition structures provide less vibration, which leads to better plate longevity, and overall cycling performance
  • 2 Year Full Replacement Warranty

    Maintenance Tips from Crown Battery - for improved longevity and cycle life:

  • The two most important tools for taking readings from your battery bank are a Hydrometer, and a Voltmeter
  • Manufacturer recommends not to have more than 2 strings per battery bank, to ensure maximum amperage in each string in a 4 hour time frame.  This way, the batteries can get to the next stage in the charging process and then start cooling down. All of this is to get the batteries back to 110% charged. 
  • Depth of Discharge on the battery bank should be no more than 50%, with 30% being ideal
  • Ideally, the battery bank in an off grid system should be at full charge by late morning/early afternoon - Voltmeter readings of 2.12V per cell AND specific gravity readings of 1.265 or higher, indicate a fully charged battery
  • The 'perfect' battery cycle for top performance is: Full charge at late morning/early afternoon - then Float/rest throughout afternoon/early evening - then Discharge throughout the night - and Recharge again in the morning/early afternoon
  • Suggested charging current is 8-12A of deliverable current, for every 100 Ah of battery ban capacity
  • Charging must restore 100% of battery charge to ensure required performance and life, and to fully charge, approximately 110% of what was removed, must be replaced.  Example:
    • 400Ah battery bank discharged to 50% DOD.  200 Ah removed, so 222 Ah must be replaced (110%)
    • 50A rated charge controller, with 60% correction = 30A of deliverable current
    • This equates to 7.4 hours to fully charge the battery bank back (222 Ah/30A)
  • Battery Cables should be sized to handle the expected load.  Table values below are for cable lengths less than 6 feet.
